1. Education and Certifications:

• A Master's degree in Computer Science, Software Engineering, Mathematics, or related fields.
• Certifications in areas related to blockchain (e.g., Ethereum Developer Certification), systems architecture, or project management would be an asset.

2. Professional Experience:

• A minimum of 10 years of experience in the IT industry, with at least 5 years in architectural roles.
• Experience in designing and implementing solutions based on distributed technology (e.g. P2P) and open-source frameworks.
• Proven experience working with blockchain, with a strong focus on Ethereum (smart contracts, dApps, DeFi, Layer-2 solutions, etc.).
• Practical knowledge of blockchain protocols: Proof of Work (PoW), Proof of Stake (PoS), and hybrid models.
• Experience managing technical teams (5-7 people), with an emphasis on mentoring, work organization, and cross-team collaboration.

3. Technical Skills:

• Programming languages: C, C++, C#, Rust, Js, Go, Python
• Ethereum: Solidity, EVM (Ethereum Virtual Machine), Layer-2 solutions (e.g., Optimism, Arbitrum), zk-rollups, ERC-20, ERC-721.
• Other blockchains: Familiarity with competing blockchain solutions (e.g., Polkadot, Cosmos) is a plus.
• Open-source: Involvement in open-source projects or experience building open-source-based solutions.
• Cloud and containerization: Experience with cloud platforms (AWS, GCP, Azure), Docker, Kubernetes.
• Virtualization: Experience with virtualization technologies such as VMware, Hyper-V, KVM, and QEMU, including setting up and managing virtual machines, as well as working with containerized and virtualized infrastructure.
• Databases: RDBMS, NoSQL, and blockchain-specific databases (e.g., IPFS).
• Security: 
• Comprehensive understanding of general security principles, including network security, data encryption, and secure application development.
• Blockchain-specific security knowledge, such as anti-Sybil mechanisms, consensus vulnerabilities (e.g., 51% attacks), re-entrancy attacks, and front-running prevention.
• Familiarity with cryptography, including asymmetric and symmetric encryption, hashing algorithms (e.g., SHA-256, Keccak-256), digital signatures, elliptic curve cryptography (ECC), zero-knowledge proofs (zk-SNARKs), and Merkle trees.

4. Project and Technical Skills:

• Distributed architecture: Experience designing scalable, distributed systems (e.g., microservices, event-driven architecture, peer-to-peer networks). Proven ability to implement P2P protocols and architectures, ensuring decentralized, fault-tolerant, and secure communication between nodes.
• Project management: Ability to manage projects end-to-end, from conceptualization through design, deployment, and optimization. Strong skills in coordinating technical teams, aligning business and technical goals, and delivering projects on time.
• DevOps: Understanding of CI/CD tools and processes, and automation in open-source and blockchain environments. Experience with infrastructure as code (IaC), continuous integration pipelines, and maintaining high availability in distributed systems.

5. Interpersonal Skills:

• Team management: Experience leading teams, providing technical support, and mentoring team members.
• Ability to work and manage teams remotely.
• Ability to make strategic technical decisions and collaborate with other leaders within the organization (e.g., product managers, CTO).
• Strong communication skills: Ability to present technical solutions in a way that's understandable to non-technical stakeholders.

6. Nice to Have:

• Experience with AI/ML
• Participation in international open-source and/or blockchain projects.
• Smart contract design: Expertise in creating, auditing, and deploying smart contracts, especially on Ethereum.

7. Languages:

• Fluency in English (both spoken and written)

8. Soft Skills:

• Strong analytical and strategic thinking skills.
• Creativity in problem-solving and the ability to work under pressure.
• End-to-End ownership: A strong sense of responsibility and accountability, with the ability to oversee projects from initial concept through to successful deployment and post-launch optimization.
• Openness to innovation and a commitment to continuous learning in the fast-evolving blockchain and decentralized technology sectors.
